MOUNTING FOR ROLLING SCREEN CONSTRUCTION.

Application led December 2, 1925. Serial No. 72,659.

y roller adapted to have a flexible element or screen wire wound thereonwherein the roller may be, moved within its bearings when the screen orflexible element is wound upon or unwound from the roller for permittingthe flexible element or screen which extends from the roller to maintaina substantially, straight and unvarying line at all times. v

Still a further object is to provide a casing adapted to contain aspring actuated roller upon which is wound a liexible element or screenwire, the roller being capable of bodily movement toward or from anopening formed in the casing through which the screen wire may bewithdrawn, the movement of the roller permitting the screen wire whichextends from the roller itself to the opening,'to remain in asubstantially straight unvarying line.

Still a further object is to provide a mounting for a spring actuatedroller which mounting is of such construction as will permit thespringaotuated roller to normally remain in one position and normallytend to move to this position. Y

vMy invention has to do particularly with the type of roller windowscreen construction shown in the Harry Dixson application for p'atentfiled May 13, 1925, Serial No. 29,960.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims and illustrated in theaccompanying drawings, in which:

Figure 1, isa plan view of a rolling win dow screen construction.

Figure 2, is a sectional view taken on line 2-2 of Figure 1, showing myimproved mounting for rollers used in rolling window screenconstruction.

Figure 3, is a sectional view taken on line 3-3 of Figure 1, showing aconsiderable amount of screen wire or other flexible element, wound uponthe roller.

Figure 4, is asimilar sectional view showing only a small amount of thescreenwire on the roller.

Figure 5, is a detail sectional view taken on line 5-5 of Figure 2 andFigure 6, is a similar view of a slightly modified form.

In the accompanying drawings I have used the reference numeral 10 toindicate generally a window frame or casing, and 11 to indicate a casingin which is contained the screen wire when in rolled-up position.

The casing l1 is formed with an opening 12 in its bottom and along oneof its sides through which the screen wire 13 may be withdrawn as I willhereinafter describe.

The casing 11 is formed with a pair of spaced bearing plates 14, formedwith elongated bearing openingsA 15. The openings 15 are curved from endto end as shown in Figure 2 of the drawings.

A shaft 16 is mounted in the openings 15 and carries a hollow roller 17thereon. -Interposed between the roller 17 and the shaft 16 is a coiledspring 18. The shaft 16, the hollow roller 17 and the spring 18 are alltermed in the explanation to follow a spring actuated roller 18a.

The screen 13 is designed to extend into a pair of guides 19 along thesides of the window frame 10 when the window screen is in withdrawnposition.

At the free edge ofA the screen is the binder strip 13, one of the.functions of which is to prevent this free edge from being drawn intothe casing.

In order to guide the mounting of the spring actuated roller 18a and toinsure its movement towards one end of the bearing opening 17, I provideguide means in theYV form or rods or wires 20, which may be pivotallyconnected with the bearing plates 14. either by extending therethroughas shown in Figure 5 of the drawings or by forming ears 21 upon thebearing plates 14 and connecting the wires 20 thereto, for permittingSlight pivotal movement of the wires 20.

The spring actuated roller 18, has a tendency to move inthe directionindicated by the arrow 22 and this tendency causes the spring actuatedroller 18l to remain in the upward position of the bearingv openings 15.

The ends of the shaft 16 are nonrotatably connected with the rods 20 andthis permits movement of they spring actuated roller within the.openings 15 relative to the wire 20.

lli

One position of the wire 20 is shown in dotted lines in Figure 2 of thedrawings. When the screen wire 13 is withdrawn from the casing ll,through the opening l2, there immediately becomes less screen wire or material upon the spring actuated roller 18a, and in order to maintain asubstantially straight unvarying line from the material upon the rolleritself to the opening l2, I have the spring actuated roller mounted formovement within its bearings.

After the screen wire 13 is withdrawn the spring actuated roller 18amoves toward the opening l2 and the screen wire when withdrawn willremain in a substantially straight unvarying line regardless ot whetherthe amount of screen wire upon the roller is lilre that illustrated inFigure 3 of the drawings or that in Figure 4 of the drawings. Y

l/Vhen the screen wire is permitted to roll up on the spring actuatedroller 18, then the normal tendency oi the spring actuated roller itselis to move to its upward position. within the bearing openings 15. Thespring actuated roller 18"-, becomes so positioned as to permit theentire cross sectional area ci the easing ll to be consumed as clearlyshown in Figure 3 oft' the drawings,

The advantage of my invention resides in the fact that the springactuated roller is mounted for movement within its bearings so thatthere is no danger of the screen wire or other flexible element frombecoming worn out or torn as it passes over the edge of the casingadjacent to the opening 12. straight line pull at all times is had bymovably mounting the spring; actuated roller 18S..

A further advantage is the use of the spring actuated roller which notonly serves to wind the screen wire up but also serves in connectionwith the yguide rods 2O and the hearing openings l5, to cause the rollerto move to its upward position within the openings l5 when the screenwire is wound upon the roller., Y

lt will be noted. that while I have described nay device for use inconnection with screen wire, that any other fienible element may he usedin lace of the screen wire, where it is desiredto get a straightunvarying line from the material itself on the roller to the openingthrough which it is drawn at all times.

Some changes may be made in the construction and arrangement of thevarious parts of my invention, without departing from the real spiritand purpose of my inventin, and it is my intention to cover by myclaims, and modified forms of structure or use of mechanicalequivalents, which may be reasonably included within their scope.
